Synopsis

Convert a string to lowercase

Description

The strlow function takes a string s and returns another string identical to s except that all upper case characters that comprise s will be converted to lower case.

Example

The function

    {
      return strcmp (strlow (a), strlow (b));
    }

performs a case-insensitive comparison operation of two strings by converting them to lower case first.
